    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Thanks! But I am currently using 12V LED strips. And it seems that multiplexing it doesn't seem to well lit especially outdoors.

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Hehehe. We are currently making this for a government project that is why I am afraid of risking it. Anyway, if there is a way to keep it safe using such method then I would really be interested in it. I would definitely appreciate it if you could enlighten me. By the way, what do you call such...

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Each segment currently draws 12 V & about 100 mA. Does that mean if I have 6 digits, I need 6 BCD to 7 Segment Decoder/Latch? Thanks for all your replies.

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Although this is not really the same with my circuit, this concept of multiplexing is what I am currently using. Instead of sourcing current from the arduino, I am using a transistor instead. By the way, could you elaborate more about what you meant by BCD to 7 seg latches. I know BCD to 7...

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    But wouldn't that be very dangerous especially when the microcontroller stop switching (just in case)? I heard that it will also reduce the led's lifetime. What should be a safer remedy? Thanks for your reply by the way.

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Hi guys! I am currently making huge 7 segment displays for our project. I am using 2 led strips for each segment. This is an outdoor project so I think I am gonna change the segments with multiple super bright LEDs. There is one problem guys the digits seem to be very dim when I try to switch it...

    Need Help in mosfet switching strobed LEDs

    Problem is now solved guys. Fortunately, I was able to find a P-Channel after days of canvassing. Thanks for all your help guys!

    Need Help in mosfet switching strobed LEDs

    The problem sir its hard to find it here. I could buy it, but I'll have to wait for a week or two which is definitely not an option considering that I have to finish this as early as possible.

    Need Help in mosfet switching strobed LEDs

    Well, in the first diagram, I switched the P-Channel Mosfet (the one that I bought) into such in the diagram and it worked. The problem is it only works as a switching Mosfet if I use it like an N-Channel Mosfet. Well, on the second diagram, I wanted to know if there was any other way that I...

    Need Help in mosfet switching strobed LEDs

    Indeed, sir! This must definitely be an N-Channel. Thanks so much for helping me point this out sir!

    Need Help in mosfet switching strobed LEDs

    I think I know what really is the problem now. For some reason, doing the mosfet testing using N-Channel procedures actually worked out well for my P-Channel Mosfet. This made me think that my P-Channel Mosfet actually has an N-Channel Mosfet characteristics. To verify it, I constructed this...

    Need Help in mosfet switching strobed LEDs

    I did the checking using this video as reference: Well, it seems fine. Four mosfets actually have the same reading. I am still gonna try the other three to the circuit. Thanks for your reply Steve by the way.

    Need Help in mosfet switching strobed LEDs

    This is what I did guys. The MOSFET is FQP27P06. For some reason, connecting the gate directly to the source (12V) won't even turn the MOSFET off. What could be the problem?

    Need Help in mosfet switching strobed LEDs

    Oh, I forgot to tell you that I have already connected the source to 12V and the Drain to the led strip. Supplying 5V to the gate won't turn it off even the 12V.

    Need Help in mosfet switching strobed LEDs

    Hi guys sorry for the late reply. I am actually doing this for a school project. I am using two drivers (P-channel and N-Channel) in order to multiplex LED's. What I am switching are just 12V LED Strips. I believe they already have current limiting resistors so I don't think I need to add it in...

    Need Help in mosfet switching strobed LEDs

    I have a bunch of High Power LEDs that are being strobed. I need to switch them using Mosfets. Well, I really have a little idea in using Mosfet that is why I carelessly only bought N-Channel Mosfets for switching them. This is how the circuit looks like: But it turns out that it does not...

    Need Help in SCR/TRIAC Project

    thanks for your reply. Hmmmm, Optocoupler. I'll definitely check that one. I'd like to control the firing angle. I'm still not sure whether I am going to use an SCR or a Triac but I would be using a motor as a load. It will be operated @ 220 V. Well, what can you suggest? Thanks!

    Need Help in SCR/TRIAC Project

    Hi! I was wondering how should I isolate my low power components from my SCR/TRIAC which controls high powered loads. We currently have a project which entails controlling high power loads using Triacs/SCRs; however, I am not sure on how do I isolate the microcontroller (which we should use in...

    Traffic Lights Circuit Help

    Thanks for your response! But I guess, our teacher was just challenging and fooling around with us. He then told us that it would be hard for us to do such a thing if we won't add a flip flop so I made this circuit with a flip flop and here is what I did: If you can suggest something about...
